Commit 2ccdd1e77da52ad494e9af46bf272d816830cb28 doesn't add
v7wbi_possible_flags and v7wbi_always_flags to possible_tlb_flags and
always_tlb_flags.  This causes the L2 cache flush in clean_pmd_entry()
(intended for Feroceon only) to execute on ARMv7, and the CPU hangs.

This patch is required for OMAP3 boards to boot.
